Hi All, For two nights I have observed Cosmos 2263 R/B (#22803), and on both occasions its magnitude was considerably dimmer than predicted. I notice that in the Molczan file its standard magnitude is 3.9. To match my observations, it would need to be dimmed to 5.1. I was able to time Lacrosse 3 R/B a little longer last night, and now come up with a period of 34.7 seconds +/- 2 seconds. It's hard to estimate it much better than this because the minima and maxima are so broad. This period is based on 4 complete cycles from max to max, with times of 35.6, 31.8, 37.3 and 34.0 seconds. Also got another timing on Superbird A: 23.128 +/- .008 seconds. While timing it, an unexpected dim satellite slowly crossed my binocular field-of-view. I later identified it as Cosmos 2088 (90-066A, #20720), which was predicted to only be at magnitude +7.5. It was at least +6.5, so I have adjusted the standard magnitude for this satellite from +6.0 to +5.0. --Rob
